Adjusting the brightness
■ Brightness adjustment using the [BRT] lever
The [BRT] lever is used to adjust the brightness when changing the overall brightness of the live
image during observation.
Pushing the [BRT] lever upward brightens the overall image and pushing it downward darkens
the image.
Brightness can be adjusted to one of the 16 different levels.
■ Switching the Gain Mode
Pressing the [LIVE] button while a live image is displayed switches the gain mode.
